CNC laser cutting is a key process utilised by metal fabrication subcontractors for the manufacture of sheet metal components and products.
It's a metal cutting technique that offers a precise metal profiling solution and delivers consistent, accurate and cost-competitive results.
Laser cutting involves cutting sheet metal using a highly precise laser beam that focuses on a tiny area of the material. Lasers offer a way of cutting metal efficiently and quickly enabling KMF to meet the ever-growing demand for high-quality metal machined products.
CNC laser cutting is often favoured for its ability to produce intricate designs, reduce material wastage and minimise changeover times. Computers allow the cutting of almost any shape and patterns are only limited by what the client can draw.
Technology allows the high-powered laser cutting of many kinds of metal including different grades of steel, vital to many industries such as the automotive and aerospace sectors.
The process is supported by computer-controlled programming that determines how and where the laser beam interacts with the material. Advances in technology have seen the introduction of laser/punch combination machines that suit fabricators who require cost-effective and flexible metal forming and cutting solutions.
The majority of leading metal fabrication subcontractors employ two types of CNC laser cutting machines, optical fibre and CO2.
Fibre laser cutting machines are members of the solid-state laser group. They create a beam using a 'seed laser' which is amplified by glass fibres supplied with energy via pump diodes.
Fiber laser cutting is used on reflective materials, is most suited to thinner materials and provides greater electrical efficiency. Fibre lasers can also be used for metal marking techniques as in laser engraving.
By comparison, C02 laser cutting machines are a type of gas laser that uses an electrically stimulated carbon dioxide mixture.
C02 lasers can be used for a range of materials, both metal and non-metal, and deliver a fast cutting rate for thicker materials.
Each type of CNC laser cutting machine has its advantages and disadvantages and metal fabrication subcontractors often employ different laser techniques for various applications.
CNC laser cutting provides a precise, versatile and fast profiling solution in metal forming design. It is ideal for intricate patterns and is extremely cost-effective.
Other advantages of laser cutting machines include:
CNC punching technology uses a set of punches and dies to punch parts out of sheet metal. CNC punching and laser cutting are the cutting techniques most commonly used by metal fabrication subcontractors.
Despite these limitations, CNC punching often delivers a more competitive and equally high-quality solution when fabricating simple component shapes in large batch sizes.
A significant advantage of CNC punching over laser cutting is its ability to achieve forms, e.g. tap, extrude, rib and louvre which cannot be replicated on a laser cutting machine.
